Mark is building a pyramid out of blocks. the top of his pyramid has 1 block, the second layer has 4 blocks, the third layer has 9 blocks, the fourth layer has 16 blocks, and the fifth layer has 25 blocks. if mark decided to add a sixth layer to his pyramid, how many blocks would that layer have?

36

Step-by-step explanation:

The difference between the first and second layer is 3, then 5, then 7, then 9, so you can deduce the next one will be 11.

25+11=36

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
